2.3            
Cashless Exercise.


 


2.3.1       
Determination of Amount. In lieu of the payment of the Exercise Price multiplied by the number of Units for which
this Purchase Option is exercisable (and in lieu of being entitled to receive Ordinary Shares and Warrants) in the manner required
by Section 2.1, and subject to Section 6.1 hereof, the Holder shall have the right (but not the obligation) to convert
any exercisable but unexercised portion of this Purchase Option into Units (“Cashless Exercise Right”)
as follows: upon exercise of the Cashless Exercise Right, the Company shall deliver to the Holder (without payment by the Holder
of any of the Exercise Price in cash) that number of Units (or that number of Ordinary Shares, Warrants and Rights comprising that
number of Units) equal to the number of Units to be exercised multiplied by the quotient obtained by dividing (x) the “Value”
(as defined below) of the portion of the Purchase Option being converted by (y) the Current Market Value (as defined below). The
“Value” of the portion of the Purchase Option being converted shall equal the remainder derived from
subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Units underlying the portion of this Purchase Option being
converted from (b) the Current Market Value of a Unit multiplied by the number of Units underlying the portion of the Purchase
Option being converted. As used herein, the term “Current Market Value” per Unit at any date means: (A)
in the event that the Units, Ordinary Shares, Public Rights and Public Warrants are still trading, (i) if the Units are listed
on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange), the average reported last sale price
of the Units in the principal trading market for the Units as reported by the exchange, Nasdaq or the Financial Industry Regulatory
Authority (“FINRA”), as the case may be, for the three trading days preceding the date in question; or
(ii) if the Units are not listed on a national securities exchange or quoted on the OTC Bulletin Board (or successor exchange),
but is traded in the residual over-the-counter market, the average reported last sale price for Units for the three trading days
preceding the date in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations;
(B) in the event that the Units are not still trading but the Ordinary Shares, Public Rights, and Public Warrants underlying the
Units are still trading, the aggregate of (i) the product of (x) the Current Market Price of the Ordinary Share and (y) the number
of the Ordinary Shares underlying one Unit (which shall include the portion of an Ordinary Share the holder of a Unit would automatically
receive in connection with the Right included in each such Unit), plus (ii) the product of (x) the Current Market Price of the
Public Warrants and (y) the number of Warrants included in one Unit; or (C) in the event that neither the Units nor the Public
Warrants are still trading, the aggregate of (i) the product of (x) the Current Market Price of the Ordinary Shares and (y) the
number of the Ordinary Shares underlying one Unit (which shall include the portion of an Ordinary Share the holder of a Unit would
automatically receive in connection with the Right included in each such Unit), plus (ii) the remainder derived from subtracting
(x) the exercise price of the Warrants multiplied by the number of Ordinary Shares issuable upon exercise of the Warrants underlying
one Unit from (y) the product of (aa) the Current Market Price of the Ordinary Shares multiplied by (bb) the number of Ordinary
Shares underlying the Warrants included in each such Unit. The “Current Market Price” shall mean (i) if the Ordinary
Shares (or Public Warrants, as the case may be) are listed on a national securities exchange or quoted on the OTC Bulletin Board
(or successor exchange), the average reported last sale price of the Ordinary Shares (or Public Warrants) in the principal trading
market for the Ordinary Share (or Public Warrants) as reported by the exchange, Nasdaq or FINRA, as the case may be, for the three
trading days preceding the date in question; (ii) if the Ordinary Shares (or Public Warrants) are not listed on a national securities
exchange or quoted on the OTC Bulletin Board (or successor exchange), but are traded in the residual over-the-counter market, the
average reported last sale price for the Ordinary Share (or Public Warrants) on for the three (3) trading days preceding the date
in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such quotations; and (iii) if
the fair market value of the Ordinary Share cannot be determined pursuant to clause (i) or (ii) above, such price as the Board
of Directors of the Company shall determine, in good faith. In the event the Public Warrants have expired and are no longer exercisable,
no “Value” shall be attributed to Warrants underlying this Purchase Options.

2.3.2       
Mechanics of Cashless Exercise. The Cashless Exercise Right may be exercised by the Holder on any business day on
or after the Commencement Date and not later than the Expiration Date by delivering the Purchase Option with the duly executed
exercise form attached hereto with the cashless exercise section completed to the Company, exercising the Cashless Exercise Right
and specifying the total number of Units the Holder will purchase pursuant to such Cashless Exercise Right


 


2.4            
No Obligation to Net Cash Settle. Notwithstanding anything to the contrary contained in this Purchase Option, in
no event will the Company be required to net cash settle the exercise of the Purchase Option or Warrants underlying the Purchase
Option. The holder of the Purchase Option and Warrants underlying the Purchase Option will not be entitled to exercise the Purchase
Option or the Warrants underlying such Purchase Option unless it exercises such Purchase Option pursuant to the Cashless Exercise
Right or a registration statement is effective, or an exemption from the registration requirements is available at such time and,
if the holder is not able to exercise the Purchase Option or underlying Warrants, the Purchase Option and/or the underlying Warrants,

not sell, transfer, assign, pledge or hypothecate this Purchase Option (or the Ordinary Shares and Warrants underlying this Purchase

any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the Purchase

Restrictions Imposed by the Act. The securities evidenced by this Purchase Option shall not be transferred unless
and until (i) the Company has received the opinion of counsel for the Holder that the securities may be transferred pursuant to
an exemption from registration under the Act and applicable state securities laws, the availability of which is established to
the reasonable satisfaction of the Company (the Company hereby agreeing that the opinion of Loeb & Loeb LLP shall be deemed
satisfactory evidence of the availability of an exemption), or (ii) a registration statement or a post-effective amendment to the
Registration Statement relating to such securities has been filed by the Company and declared effective by the Securities and Exchange
Commission (the “Commission”) and compliance with applicable state securities law has been established.

to this Purchase Option in the name of the Holder evidencing the right of the Holder to purchase the number of Units purchasable
hereunder as to which this Purchase Option has not been exercised or assigned


 


4.2            
Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation
of this Purchase Option and of reasonably satisfactory indemnification or the posting of a bond, the Company shall execute and
deliver a new Purchase Option of like tenor and date. Any such new Purchase Option executed and delivered as a result of such loss,

5.               
REGISTRATION RIGHTS.


 


5.1            
Demand Registration.


 


5.1.1       
Grant of Right. The Company, upon written demand (“Initial Demand Notice”) of the Holder(s)
of at least 51% of the Purchase Option and/or the underlying Units and/or the underlying securities (“Majority Holders”),
agrees to use its best efforts to register (the “Demand Registration”) under the Act on one occasion,
all or any portion of the (i) Purchase Option requested by the Majority Holders in the Initial Demand Notice and all of the securities
underlying such Purchase Option, including the Units, Ordinary Shares, Warrants and the Ordinary Shares underlying the Warrants
and (ii) the units issued to the Holder prior to or concurrently with the Offering and all the securities underlying such units
(collectively, the “Registrable Securities”). On such occasion, the Company will use its best efforts
to file a registration statement or a post-effective amendment to the Registration Statement covering the Registrable Securities
as expeditiously as possible after receipt of the Initial Demand Notice and use its best efforts to have such registration statement
or post-effective amendment declared effective as soon as possible thereafter. The demand for registration may be made at any time
during a period of four and one-half years beginning 180 days after the Effective Date. The Initial Demand Notice shall specify
the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company
will notify all holders of the Purchase Option and/or Registrable Securities of the demand within ten days from the date of the
receipt of any such Initial Demand Notice. Each holder of Registrable Securities who wishes to include all or a portion of such
holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in
such registration, a “Demanding Holder”) shall so notify the Company within fifteen (15) days after the
receipt by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their
Registrable Securities included in the Demand Registration, subject to Section 5.1.4. The Company shall not be required
to effect more than one (1) Demand Registration under this Section 5.1 in respect of all Registrable Securities.


 


5.1.2       
Effective Registration. Notwithstanding Section 5.1.5, a registration will not count as a Demand Registration
until the registration statement filed with the Commission, with respect to such Demand Registration, has been declared effective
and the Company has complied with all of its obligations under this Purchase Option with respect thereto.


 


5.1.3       
Underwritten Offering. If the Majority Holders so elect and such holders so advise the Company as part of the Initial
Demand Notice, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten
offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned
upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in
the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their securities through such underwriting
shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting
by the Majority Holders.


 


5.1.4       
Reduction of Offering. If the managing underwriter or underwriters for a Demand Registration that is to be an underwritten
offering advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities
which the Demanding Holders desire to sell, taken together with all other Ordinary Shares or other securities which the Company
desires to sell and the Ordinary Shares, if any, as to which registration has been requested pursuant to written contractual piggy-back
registration rights held by other shareholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum
number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution
method, or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable,
the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first, the
Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with
the number of shares that each such person has requested be included in such registration, regardless of the number of shares held
by each such person (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding
the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clause (i), the Ordinary Shares or other securities that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses
(i) and (ii), the Ordinary Shares or other securities registrable pursuant to the terms of the Registration Rights Agreement between
the Company and the initial investors in the Company and Chardan, dated as of [__________],[3]
2018 (the “Registration Rights Agreement” and such registrable securities, the “Investor
Securities”) as to which “piggy-back” registration has been requested by the holders thereof, Pro Rata,
that can be sold without exceeding the Maximum Number of Shares; and (iv) fourth, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clauses (i), (ii), and (iii), the Ordinary Shares or other securities for the account
of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons and that
can be sold without exceeding the Maximum Number of Shares.

5.1.5       
Withdrawal. If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are
not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders
may elect to withdraw from such offering by giving written notice to the Company and the underwriter or underwriters of their request
to withdraw prior to the effectiveness of the registration statement filed with the Commission with respect to such Demand Registration.
If the majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then
the Company does not have to continue its obligations under Section 5.1, provided that, any such withdrawal will
not count as the Demand Registration if the Demanding Holders pay all of the Company’s out-of-pocket expenses, with respect
to such withdrawn registration.


 


5.1.6       
Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including
the expenses of one legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities,
but the Holders shall pay any and all underwriting commissions. The Company agrees to use its reasonable best efforts to qualify
or register the Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however,
that in no event shall the Company be required to register the Registrable Securities in a state in which such registration would
cause (i) the Company to be obligated to qualify to do business in such state, or would subject the Company to taxation as a foreign
corporation doing business in such jurisdiction or (ii) the principal shareholders of the Company to be obligated to escrow their
shares of capital stock of the Company. The Company shall use its best efforts to cause any registration statement or post-effective
amendment filed pursuant to the demand rights granted under Section 5.1.1 to remain effective for a period of nine consecutive
months from the effective date of such registration statement or post-effective amendment.


 


5.2            
Piggy-Back Registration.


 


5.2.1       
Piggy-Back Rights. If at any time during the seven year period commencing on the Effective Date the Company proposes
to file a registration statement under the Act with respect to an offering of equity securities, or securities or other obligations
exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for shareholders
of the Company for their account (or by the Company and by shareholders of the Company including, without limitation, pursuant
to Section 5.1), other than a registration statement (i) filed in connection with any employee stock option or other benefit
plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering
of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall
(x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event
less than ten (10) days before the anticipated filing date, which notice shall describe the amount and type of securities to be
included in such offering, the intended method(s) of distribution, and the name of the proposed managing underwriter or underwriters,
if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the
sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) days following receipt
of such notice (a “Piggy-Back Registration”). The Company shall cause such Registrable Securities to
be included in such registration and shall use its best efforts to cause the managing underwriter or underwriters of a proposed
underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms
and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities
in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute
their securities through a Piggy-Back Registration that involves an underwriter or underwriters shall enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for such Piggy-Back Registration


 


5.2.2       
Reduction of Offering. If the managing underwriter or underwriters for a Piggy-Back Registration that is to be an
underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number
of Ordinary Shares which the Company desires to sell, taken together with Ordinary Shares, if any, as to which registration has
been demanded pursuant to written contractual arrangements with persons other than the holders of Registrable Securities hereunder,
the Registrable Securities as to which registration has been requested under this Section 5.2, and the Ordinary Shares,
if any, as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other
shareholders of the Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration:

has not been reached under the foregoing clauses (A), (B) and (C), the Ordinary Shares or other securities for the account of other
persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold
without exceeding the Maximum Number of Shares; and


 


(c)       If
the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable
Securities or of Investor Securities, (A) first, the Ordinary Shares or other securities for the account of the demanding persons
that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has
not been reached under the foregoing clause (A), the Ordinary Shares or other securities that the Company desires to sell that
can be sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not
been reached under the foregoing clauses (A) and (B), collectively the Ordinary Shares or other securities comprised of Registrable
Securities and Investor Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof and of the
Registration Rights Agreement, as applicable, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth,

5.2.3       
Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion
of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior
to the effectiveness of the registration statement. The Company (whether on its own determination or as the result of a withdrawal
by persons making a demand pursuant to written contractual obligations) may withdraw a registration statement at any time prior
to the effectiveness of the registration statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred
by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 5.2.4.


 


5.2.4       
Terms. The Company shall bear all fees and expenses attendant to registering the Registrable Securities, including
the expenses of one legal counsel selected by the Holders to represent them in connection with the sale of the Registrable Securities
but the Holders shall pay any and all underwriting commissions related to the Registrable Securities. In the event of such a proposed
registration, the Company shall furnish the then Holders of outstanding Registrable Securities with not less than fifteen days
written notice prior to the proposed date of filing of such registration statement. Such notice to the Holders shall continue to
be given for each applicable registration statement filed (during the period in which the Purchase Option is exercisable) by the
Company until such time as all of the Registrable Securities have been registered and sold. The Holders of the Registrable Securities
shall exercise the “piggy-back” rights provided for herein by giving written notice within ten days of the receipt
of the Company’s notice of its intention to file a registration statement. The Company shall use its best efforts to cause
any registration statement filed pursuant to the above “piggyback” rights to remain effective for at least nine months

in investigating, preparing or defending against any claim whatsoever) to which they may become subject under the Act, the Exchange
Act or otherwise, arising from information furnished by or on behalf of such Holders, or their successors or assigns for specific
inclusion in such registration statement or arising from any omission or the alleged omission to state a material fact required
to be stated therein or necessary to make the statement contained therein not misleading in connection with the registration of
the Registrable Securities, to the same extent and with the same effect as the provisions contained in Section 5 of the Underwriting
Agreement pursuant to which the underwriters have agreed to indemnify the Company.


 


5.3.2       
Exercise of Purchase Option. Nothing contained in this Purchase Option shall be construed as requiring the Holder(s)
to exercise their Purchase Option or Warrants underlying such Purchase Option prior to or after the initial filing of any registration
statement or the effectiveness thereof.


 


5.3.3       
Documents Delivered to Holders. The Company shall furnish Chardan, for as long as it is a Holder, as representative
of the Holders participating in any of the foregoing offerings, a signed counterpart, addressed to the participating Holders, of
(i) an opinion of counsel to the Company, dated the effective date of such registration statement (and, if such registration includes
an underwritten public offering, an opinion dated the date of the closing under any underwriting agreement related thereto), and
(ii) a “cold comfort” letter dated the effective date of such registration statement (and, if such registration includes
an underwritten public offering, a letter dated the date of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company’s financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such registration statement (and the prospectus included therein)
and, in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements,
as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in
underwritten public offerings of securities. The Company shall also deliver promptly to Chardan, as representative of the Holders
participating in the offering, the correspondence and memoranda described below and copies of all correspondence between the Commission
and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit Chardan, as representative of the Holders, to do such investigation, upon reasonable advance
notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to
comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties
and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent
and at such reasonable times and as often as Chardan, as representative of the Holders, shall reasonably request. The Company shall
not be required to disclose any confidential information or other records to Chardan, as representative of the Holders, or to any
other person, until and unless such persons shall have entered into reasonable confidentiality agreements (in form and substance
reasonably satisfactory to the Company), with the Company with respect thereto.

5.3.4       
Underwriting Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s),
if any, selected by any Holders whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter
shall be reasonably acceptable to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company,
each Holder and such managing underwriters, and shall contain such representations, warranties and covenants by the Company and
such other terms as are customarily contained in agreements of that type used by the managing underwriter. The Holders shall be
parties to any underwriting agreement relating to an underwritten sale of their Registrable Securities and may, at their option,
require that any or all the representations, warranties and covenants of the Company to or for the benefit of such underwriters
shall also be made to and for the benefit of such Holders. Such Holders shall not be required to make any representations or warranties
to or agreements with the Company or the underwriters except as they may relate to such Holders and their intended methods of distribution.
Such Holders, however, shall agree to such covenants and indemnification and contribution obligations for selling shareholders
as are customarily contained in agreements of that type used by the managing underwriter. Further, such Holders shall execute appropriate
custody agreements and otherwise cooperate fully in the preparation of the registration statement and other documents relating
to any offering in which they include securities pursuant to this Section 5. Each Holder shall also furnish to the Company such
information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities
as shall be reasonably required to effect the registration of the Registrable Securities.


 


5.3.5       
Rule 144 Sale. Notwithstanding anything contained in this Section 5 to the contrary, the Company shall have
no obligation pursuant to Sections 5.1 or 5.2 to use its best efforts to obtain the registration of Registrable Securities
held by any Holder (i) where such Holder would then be entitled to sell under Rule 144 within any three-month period (or such other
period prescribed under Rule 144 as may be provided by amendment thereof) all of the Registrable Securities then held by such Holder,
or (ii) where the number of Registrable Securities held by such Holder is within the volume limitations under paragraph (e) of
Rule 144 (calculated as if such Holder were an affiliate within the meaning of Rule 144).


 


5.3.6       
Supplemental Prospectus. Each Holder agrees, that upon receipt of any notice from the Company of the happening of
any event as a result of which the prospectus included in the registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, such Holder will immediately discontinue disposition of Registrable
Securities pursuant to the registration statement covering such Registrable Securities until such Holder’s receipt of the
copies of a supplemental or amended prospectus, and, if so desired by the Company, such Holder shall deliver to the Company (at
the expense of the Company) or destroy (and deliver to the Company a certificate of such destruction) all copies, other than permanent
file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time
of receipt of such notice.


 


6.               
ADJUSTMENTS.


 


6.1            
Adjustments to Exercise Price and Number of Securities. The Exercise Price and the number of Units underlying the
Purchase Option shall be subject to adjustment from time to time as hereinafter set forth:


 


6.1.1       
Stock Dividends - Split-Ups. If after the date hereof, and subject to the provisions of Section 6.3 below,
the number of outstanding Ordinary Shares is increased by a stock dividend payable in Ordinary Shares or by a split-up of Ordinary
Shares or other similar event, then, on the effective date thereof, the number of Ordinary Shares underlying each of the Units
purchasable hereunder shall be increased in proportion to such increase in outstanding shares. In such case, the number of Ordinary
Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of the Units purchasable hereunder shall
be adjusted in accordance with the terms of the Warrants.


 


6.1.2       
Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 6.3, the number
of outstanding Ordinary Shares is decreased by a consolidation, combination or reclassification of Ordinary Shares or other similar
event, then, on the effective date thereof, the number of Ordinary Shares underlying each of the Units purchasable hereunder shall
be decreased in proportion to such decrease in outstanding shares and the Exercise Price shall be proportionately increased. In
such case, the number of Ordinary Shares, and the exercise price applicable thereto, underlying the Warrants underlying each of
the Units purchasable hereunder shall be adjusted in accordance with the terms of the Warrants.


 


 


 






    	 	8	 



     


    

 


6.1.3       
Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding
Ordinary Shares other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely affects the par value
of such Ordinary Shares, or in the case of any merger or consolidation of the Company with or into another company (other than
a consolidation or merger in which the Company is the continuing entity and that does not result in any reclassification or reorganization
of the outstanding Ordinary Shares), or in the case of any sale or conveyance to another company or entity of the property of the
Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this Purchase
Option shall have the right thereafter (until the expiration of the right of exercise of this Purchase Option) to receive upon
the exercise hereof, for the same aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount
of shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation,
or upon a dissolution following any such sale or transfer, by a Holder of the number of Ordinary Shares of the Company obtainable
upon exercise of this Purchase Option and the underlying Warrants immediately prior to such event; and if any reclassification
also results in a change in Ordinary Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made
pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.


 


6.1.4       
Changes in Form of Purchase Option. This form of Purchase Option need not be changed because of any change pursuant
to this Section, and a Purchase Option issued after such change may state the same Exercise Price and the same number of Units
as are stated in the Purchase Option as initially issued. The acceptance by any Holder of the issuance of a new Purchase Option
reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement
Date or the computation thereof.


 







6.2            
Substitute Purchase Option. In case of any consolidation of the Company with, or merger of the Company with, or merger
of the Company into, another entity (other than a consolidation or merger which does not result in any reclassification or change
of the outstanding Ordinary Shares), the entity formed by such consolidation or merger shall execute and deliver to the Holder
a supplemental Purchase Option providing that the holder of each Purchase Option then outstanding or to be outstanding shall have
the right thereafter (until the stated expiration of such Purchase Option) to receive, upon exercise of such Purchase Option, the
kind and amount of shares and other securities and property receivable upon such consolidation or merger, by a holder of the number
of Ordinary Shares of the Company for which such Purchase Option might have been exercised immediately prior to such consolidation,
merger, sale or transfer. Such supplemental Purchase Option shall provide for adjustments which shall be identical to the adjustments
provided in Section 6. The above provision of this Section shall similarly apply to successive consolidations or mergers.


 


6.3            
Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions
of Ordinary Shares or Warrants upon the exercise of the Purchase Option, nor shall it be required to issue scrip or pay cash in
lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding
any fraction up or down to the nearest whole number of Warrants, Ordinary Shares or other securities, properties or rights.


 


7.               
RESERVATION AND LISTING. The Company shall at all times reserve and
keep available out of its authorized but unissued Ordinary Shares, solely for the purpose of issuance upon exercise of the Purchase
Option (including the Ordinary Shares underlying the Rights) or the Warrants, such number of Ordinary Shares or other securities,
properties or rights as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the
Purchase Option and payment of the Exercise Price therefor, all Ordinary Shares and other securities issuable upon such exercise
shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any shareholder. The Company
further covenants and agrees that upon exercise of the Warrants underlying the Purchase Option and payment of the respective Warrant
exercise price therefor, all Ordinary Shares and other securities issuable upon such exercise shall be duly and validly issued,
fully paid and non-assessable and not subject to preemptive rights of any shareholders. As long as the Purchase Option shall be
outstanding, the Company shall use its best efforts to cause all (i) Units and Ordinary Shares issuable upon exercise of the Purchase
Option, (ii) Warrants issuable upon exercise of the Purchase Option (iii) Ordinary Shares issuable upon exercise of the Warrants
included in the Units issuable upon exercise of the Purchase Option, (iv) Rights issuable upon exercise of the Purchase Option
and (v) Ordinary Shares underlying the Rights included in the Units issuable upon exercise of the Purchase Option to be listed
and/or quoted (subject to official notice of issuance) on all securities exchanges (or, if applicable, on the OTC Bulletin Board
or OTC Markets Group, Inc. or any successor trading market) on which the Ordinary Shares or the Public Warrants may then be listed
and/or quoted.

8.               
CERTAIN NOTICE REQUIREMENTS.


 


8.1            
Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right
to vote or consent as a shareholders for the election of directors or any other matter, or as having any rights whatsoever as a
shareholders of the Company. If, however, at any time prior to the expiration of the Purchase Option and its exercise, any of the
events described in Section 8.2 shall occur, then, in each such event, the Company shall give written notice of such event

of the shareholders entitled to such dividend, distribution, conversion or exchange of securities or subscription rights, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify such record date or the date of
the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company shall deliver to each Holder

given to the shareholders.


 


8.2            
Events Requiring Notice. The Company shall be required to give the notice described in this Section 8 upon one or
more of the following events: (i) if the Company shall take a record of the holders of its Ordinary Shares for the purpose of entitling

than out of retained earnings, as indicated by the accounting treatment of such dividend or distribution on the books of the Company,
or (ii) the Company shall offer to all the holders of its Ordinary Shares any additional shares of capital stock of the Company
or securities convertible into or exchangeable for shares of capital stock of the Company, or any option, right or warrant to subscribe
therefor, or (iii) a dissolution, liquidation or winding up of the Company (other than in connection with a consolidation or merger)
or a sale of all or substantially all of its property, assets and business shall be proposed.


 







8.3

9.               
MISCELLANEOUS.


 


9.1            
Amendment The Company and Chardan, for as long as it is a Holder, may from time to time supplement or amend this
Purchase Option without the approval of any of the Holders in order to cure any ambiguity, to correct or supplement any provision
contained herein that may be defective or inconsistent with any other provisions herein, or to make any other provisions in regard
to matters or questions arising hereunder that the Company and Chardan may deem necessary or desirable and that the Company and
Chardan deem shall not adversely affect the interest of the Holders. All other modifications or amendments shall require the written
consent of and be signed by the party against whom enforcement of the modification or amendment is sought.


 


9.2            
Headings. The headings contained herein are for the sole purpose of convenience of reference, and shall not in any
way limit or affect the meaning or interpretation of any of the terms or provisions of this Purchase Option.


 


9.3            
Entire Agreement. This Purchase Option (together with the other agreements and documents being delivered pursuant
to or in connection with this Purchase Option) constitutes the entire agreement of the parties hereto with respect to the subject
matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject
matter hereof.


 


9.4            
Binding Effect. This Purchase Option shall inure solely to the benefit of and shall be binding upon the Holder and
the Company and their permitted assignees, respective successors, legal representative and assigns, and no other person shall have
or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Purchase Option
or any provisions herein contained.


 


9.5            
Governing Law; Submission to Jurisdiction. This Purchase Option shall be governed by and construed and enforced in
accordance with the laws of the State of New York, without giving effect to conflict of laws principles thereof. Each of the Holder
and the Company hereby agrees that any action, proceeding or claim against it arising out of, or relating in any way to this Purchase
Option shall be brought and enforced in the New York Supreme Court, County of New York, or in the United States District Court
for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. Each
of the Holder and the Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient
forum. Any process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified
mail, return receipt requested, postage prepaid, addressed to it at the address set forth in Section 8.4 hereof. Such mailing
shall be deemed personal service and shall be legal and binding upon the Company in any action, proceeding or claim. The Company
and the Holder agree that the prevailing party(ies) in any such action shall be entitled to recover from the other party(ies) all
of its reasonable attorneys' fees and expenses relating to such action or proceeding and/or incurred in connection with the preparation
therefore.


 


9.6            
Waiver, Etc. The failure of the Company or the Holder to at any time enforce any of the provisions of this Purchase
Option shall not be deemed or construed to be a waiver of any such provision, nor to in any way affect the validity of this Purchase
Option or any provision hereof or the right of the Company or any Holder to thereafter enforce each and every provision of this
Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of any of the provisions of this Purchase Option shall
be effective unless set forth in a written instrument executed by the party or parties against whom or which enforcement of such
waiver is sought; and no waiver of any such breach, non-compliance or non- fulfillment shall be construed or deemed to be a waiver
of any other or subsequent breach or non-compliance.


 


9.7            
Execution in Counterparts. This Purchase Option may be executed in one or more counterparts, and by the different
parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall
constitute one and the same agreement, and shall become effective when one or more counterparts has been signed by each of the
parties hereto and delivered to each of the other parties hereto.


 


9.8            
Exchange Agreement. As a condition of the Holder’s receipt and acceptance of this Purchase Option, Holder agrees
that, at any time prior to the complete exercise of this Purchase Option by Holder, if the Company and Chardan enter into an agreement
(“Exchange Agreement”) pursuant to which they agree that all outstanding Purchase Option’s will
be exchanged for securities or cash or a combination of both, then Holder shall agree to such exchange and become a party to the
Exchange Agreement.
